岩石孔隙按大小分组后,每一组孔隙的氢核弛豫时间可以用球管孔隙模型计算。
All pores are divided into different groups by their radii, and the relaxation time of each group can be calculated with the sphere-capillary model.
结果:灰质核团t2弛豫时间随脑铁含量增加而缩短,脑白质t 2弛豫时间无变化趋势。
Results: T2 relaxation time of gray matter nucleus was shorten because of iron content increasing, and that of white matter had not this change.
